plaster orsurfacing compoas it is apparent that many changes and variations maybe madetherein, bv those skilled in the art, without departing from the splrit *of the invention, or exceeding the scope'off the appended claims. "Iclaim:-"

1. A'floor construction comprising a supporting metallic framework, flanges on the lower side of, the framework, pre-cast slabs adapted to rest on the inner side of said flanges, hardening material poured on top of the slabs and lying against the slabs and framework, metallic laths resting on the upper side of the supportingmetallic framework, a composition layer poured over said laths and covering them, cleats of relatively soft material laid on the composition layer, and a layer of boards supported by the cleats. i 2A floor construction comprising, U- shaped beams, pre-cast slabs bearing against the lower flanges of the U-shaped beam, a

hardening material filling the pocket formed by the U'-shaped beams and the "slab, transverse metallic laths spanning the U-shaped beams, and a composite floor covering and incasing the laths. ,7

31A .floor construction comprising, U- shaped metallic beams, precast slabs bearing against the lowerflanges of the U-shaped beams, a hardening-material enclosing the spaces between the U-shap'ed beams and bearing against the' pre' cast slabs, metallic laths bearing upon the 'U-shaped beams and spanning the spaces between the beams, a composite covering over the laths and a Wood flooring over the composite covering.

4.;A floor construction comprising, U- shaped metallic beams with central flanges,

pre-cast slabs adapted to rest upon the centralflanges, a hardening material having a bearing upon the'pre-cast slabs and filling the spaces between the beam, metallic laths transverse w th respect to the beams, a composite coverover the laths, cleats embedded in the composite covering and a wood flooring secured to the cleats.

5. In a floor construction comprising, a series of U-shaped metallic beams, a reinforcing beam comprising a U-shaped beam with a central flange, pre-cast slabs supported by the lower flanges of the U-shaped beams and central flange of the reinforcing beam, a hardening material filling the spaces between the beams and bearing upon the pro-cast slabs, transverse metallic lathing bearing against the beams, equally spaced cleats between the lathing, a composite covering enclosing the spaces between the cleats and interlocking with the lathing and a flooring supported by the cleats.

6. A floor 'constructioncomprising, a series ofU-shaped metallic beams placed back to back and equally spaced, reinforcing beams comprising a U-shaped-beam with central flanges, the central flanges'being on a line with the bottom flange of the first mentioned beams, pre-cast slabs bearing upon the central flanges of the reinforcing beam and uponthe lower flange of the adjacent beams, a hardening material enclosing the space between the beamsand bearingupon the precast slab, transverse metallic lathing bearing upon the beams, cleatssupported by the lathing, a composite covering filling the spaces between the cleats and interlocking with the lathing and a floor bearing against the cleats.

7. A floor construction comprising, a plurality of U-shaped beams, a plurality of reinforcing beams comprising U-shaped plates with central flange, pre-cast slabs bearing against the central flange and the lower flanges of the adjacent beams, a hardening material between the beams, a coveringfor the lower half of the reinforcing beam and a floor supported by'the beams and hardening material between therbeams.

8. A floor construction comprising, a plurality of U-shaped beams and reinforcing beams, the reinforcing beams having a'central flange, pre-cast slabs bearing against the centrl flange of thereinforcing beams and the lower flange of the adjacent beams, a hardening material enclosing the pockets formed between the beams and pre-cast slabs, metallic lathing laid transverse with respect to the U-shaped beams, a series ofparallel cleats embedded between the laths, a composite covering intermediate with the cleats and interlocking with the laths and a floor ing laid transverse to and upon the cleats.

In testimony whereof I afiix my signature.
